SWINGING WINDOW.

SPECIFICATION forming part of Letters Patent No. 549,453, datedNovember5, 1895.

Application filed August 2, 1895. Serial No. 557,967. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE IRLAM, of New York, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Swinging WVindows, of which the following is a full, clear, and exactdescription. v

This invention relates to vertically-sliding window sash, having meanswhereby the same may be swung; inward and the object is to provide asimple and easily-operated means whereby the sash or. window may beswung inward, so that the outer side of the glass may be cleaned by aperson standing in a room, thus avoidin g the danger incident tostanding on the outside or on the windowledge.

I will describe a swinging window embodying my improvement, and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front or inside elevation. of a window sash and frameembodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1.Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4: is a View of aportion of the casing and sash, on an enlarged scale, with certain partsbroken away to more clearly show other parts. Fig. 5 is a section on theline 5 5 of Fig. 4, and Fig. 6 is a perspective view showing a hingemechanism employed.

Referring to the drawings, A designates the inner side of awindow-casing, A the lower sash, and A the upper sash. These parts aresubstantially of the ordinary construction, and the sash are adapted toslide vertically in the casing. Each sash, however, is adapted to swinginward on hinge mechanism at one side of the sash. A hinge-pintle a issecured to the inner surface of a side rail of the sash A near its top,and this pintle is adapted to engage in asocket or keeper a, secured tothe inner surface or on the stop-bead of the casing. At its lower endthe side rail has attached to it a downwardlyextended pintle a adaptedto pass through a hole a in a plate a, secured to the sill A and into arecess a formed in said sill. The lower end of the pintle a? has alateral extension at, which may pass through a slotopeningcfl, extendedlaterally from the hole a in the plate a.

The upper sash A has a pintle 1) attached to one of its side rails,adapted to engage in a socket b, secured to the parting-bead of thecasing at a point slightly above the top of the lower sash when saidlower sash is in its downward closed position, and to the lower end ofsaid side rail is secured a downwardly-extended pintle 5 adapted toengage in a socket or keeper 11 secured to the lower portion of theparting-bead. keeper b is provided with a lateral slot-opening for thepassage of the lateral extension 1) on the lower end of the pintle b Thepintles of the sash A are suiiiciently long to allow a slight upwardmovement of the sash to clear its bottom rail from the sill withoutdisengaging the pintles'from the sockets or keepers.

I The hinge edge of the sash A has a sashcord a secured to it, and thiscord passes over a pulley to a sash-weight in the usual manner, and thehinge edge of the upper sash has attached to it a sash-cord b extendedover a pulley to a weight.

0 is a block adapted to slide in the channel of 'the casing formed bythe stop and parting beads of the casing at the side opposite the hingeedge of the sash, and this block is attached to the sash-cord c. Theblock extends outward beyond the surface of said beads, and thisextended portion is adapted to engage in a recess 0-, formed in the siderail 0 of the sash, and this recess opens or extends to the outersurface of the rail. WVhen the block 0 is within the recess 0, its upperend will engage with the upper end wall of the recess 0, as indicated inFig. 4, and then the sash may be moved up and down in the usual manner.The recessed edge of the rail 0 has a block 0 designed to engage betweenthe stop and parting beads in order to properly retain and guide thesash in its vertical movements, and to allow the sash to swing outwardthe stop-bead is cut away, as at c, to allow the passage of the block 0I will now describe means for retaining the sliding block 0 against thedraft of the sashweight when it is desired to swing the sash inward.

This-socket or D is a latch pivoted between its ends to thewindow-casing and adapted when turned in a substantially horizontalposition to extend its lower end above and across the line of movementof the block C and to engage the upper end wall of a recess (1, formedin the parting-bead. The latch D has a notch (1 formed in its upper end,into which a pivoted locking-plate D may pass when the latch is in itsvertical or out of its engaging position with the sliding block. The endof the latch is cam-shaped, as indicated at (P, to automatically raisethe locking-plate by engaging therewith when the latch is turned to its"ertical position. After the cam-surface shall have passed thelocking-plate the said plate will fall by gravity into the notch (Z.

The several retaining and locking devices for the upper sash are likesaid parts just described, excepting that the latch D for the slidingblock of the upper sash is shown as provided with a cam-shaped lower orinner end cl to engage over the sliding block.

In operation, when the sash A is in its lowermost position, the latch. Dis to be turned on its pivot to the position shown in Fig. 2. Then thesash is raised sufiiciently to clear its lower rail from the sill andbring the upper end of the block 0 against the latch. \Vhen the partsare in this position, the sash may be swung inward on its hinges, andthe'extension a on the pintle a, by engaging the under side of the platea will prevent the upward movement of the sash under the influence ofthe weight. The upper sash may be swung inward in the same manner afterengaging the pintles I) b with the sockets Z1 1)".

l'laving thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination with a casing, of a sashadapted to slide vertically therein, a detachable hinge connectionbetween the casing and sash, a sliding block attached to a weighted sashcord and adapted to engage with the upper end wall of a recess formed inthe sash, and means for holding said block when the sash is out ofengagementtherewith, substantially as specified.

2. The combination with a casing, of a sash adapted to slide verticallytherein, and also adapted to have a laterally swinging connection withsaid casing, a slidingblock attached to a weighted sash cord at the sideof the sash opposite the hinge side and adapted to engage directly withthe sash, a latch movable above and across the line of movement of saidblock and a guide block secured to the sash adapted to engage betweenthe stop and parting bead of the casing at the side engaged by thesliding block, substantially as specified.

The combination with a casin g, and a sash adapted to slide and to swingtherein, of the sliding block attached to a weighted sash cord, thelatch for securing said block pivoted between its ends to the casingand. having the cam shaped and notched end, and the locking plate forsaid latch when the latch is in its vertical position, substantially asspecified.

l. The combination with a casin g, oli'a sash movable verticallytherein, a hinge pintle secured to the sash and having a lateralextension, and a socket for receiving said pintle having a lateralopening through which said extension may pass, substantially asspecified.

5. The combination with a casing, of a sash having a detachable hingeconnection at one side with the casing, a weighted sash cord havingdirect connection with the sash at its hinge edge, the opposite siderail of said sash having a recess formed in it, the stop bead having thecut awayportion, the parting bead having a recess formed in it, theslidin block attached to a sash cord and movable between the stop andparting beads and projeeted beyond the surface thereof to engage in therecess in the sash, the latch pivoted to the stop bead and movableacross the line of movement of the sliding block and into the recess inthe partin g bead, and a locking plate for the latch, substantially asspecified.
